Got my Akras today and installed
ran around terrorizing neighborhood a little and they sound great !! .....well one at least...see below
Definitely felt some difference
Couple of things; lots of popping on deceleration, and when removing the inserts,
the retaining bolt that holds it in place was slightly spot welded to the exhaust.
They spot weld the flang that holds this bolt and must have slightly got some of the bolt head.
The left one broke loose, the right one didn't, and I striped the bolt.
Got out the dremel and carefully ground/cut off the weld and bolt came out easily.
Then I couldn't get the insert out . So I have one insert in one out. I pulled and tugged and it won't budge.
I had hoped after riding, it might heat up and could get it out...nope. Arrrg ! Not sure what to try next
